Document Summary
Canadian forest ecosystem classi cation: vegetation characteristics, regional climate, site-speci c moisture and nutrient regimes, underlying ecological processes, 1,000 standardized forest and woodland associations, involves 3 things for classi cation, 1. ) Ecozones: canadian terrestrial ecozones what makes us divide them up besides vegetation, parent material, 2. ) Alberta ecological classi cation: 6 natural regions, 21 natural subregions, these are mainly determined by, latitude, elevation, climate, soil depth (ne alberta only, which lead to, broad-scale vegetation types (the regions and subregions) Aw-sw (aspen-white, spruce-white): plant community type: speci c association of species coding ecocide phase with decimal; [e. g. d2. 2, edatopic grid: ecosites located along gradients of moisture & nutrients, 2 axis: moisture regime and nutrient regime. Indicator plants: species with narrow af nity for nutrient and moisture conditions (e. g. species b is better than g, several species with similar site requirements will strengthen the association (e. g. i and j, used to determine ecosite.
